I went to see another Tree of Death, where his highness slaughters criminals in the same way as mentioned under the other tree. The space beneath the boughs is also swept clean. This tree is more spreading, and of another sort; it is crowned with the filthy vultures, which roost day and night in considerable numbers on its upper branches. Yusuf tells me the history of these trees, when the inhabitants were pagans. It was under them that the people sacrificed their oxen and sheep to the deity, who was supposed to reside in these trees. Scarcely a generation has elapsed since this was the case, so that the people may well dread to venture where, in the time of old men yet living, sacrifices, some perhaps human, were offered up. The Sheikh is obliged to keep a tight hand over the inhabitants of Zinder, to prevent them from lapsing into paganism. His father made them Muslims, and he holds them to the profession of Islamism. No news from Tesaoua respecting the four persons who were sent to bring Drs. Barth and Overweg first to Bornou, before they went to Soudan. I have had several patients, but ophthalmia does not prevail here as in Damerghou. A constant succession of visitors troubled me all day long. Another son of the Sultan came this morning--quite a young man--and a dozen of boys from the palace, some sons of the Sultan, and others of his ministers. I gave them all a little piece of white sugar, and sent them off. This is the cheapest present. I am told that all the Tuaricks are dreadfully afraid of the Sultan of Zinder, for whenever his highness catches an offender, let him be of what tribe of Tuaricks he may, he cuts off his head with as much unconcern as a poulterer of Leadenhall market does that of a goose. I hear now that, since the dispersion of the Walad Suleiman, the route of Bornou, from Kuka to the Tibboos, is quite secure. Some lemons have been brought to me, equal in flavour, though small, to those of the north coast. In Soudan they are marvellously cheap; ten are sold at Kanou for the fiftieth part of a penny, viz. one wadâ; for the same single wadâ forty can be had at Kashna. There are forests of lemon-trees in Soudan. The news has arrived from the salt-caravan, that Barth says that he will not return even if they threaten to cut his throat. En-Noor is at Tesaoua, and says they should return; but the salt-caravan is distant from him, and the communication between the two places is difficult.--I had scarcely written these words when the four people sent to bring back Drs. Barth and Overweg returned without them, and brought letters from my colleagues, each one stating that he should continue his journey as previously determined. Ferajee, one of the messengers, pretends that En-Noor is going with Overweg to Maradee; which is very unlikely. Dr. Barth seems very angry, but his comrade takes matters more easily.
